This has been happening since i got the car but it seems like its getting worse now. The tranny is whining when you start getting past about 2k rpm. And if i shift it fast from 3rd to 4th basically everytime it goes to 4th it grinds, only when i shift it fast though. Shifting normal its ok but the whining in the tranny has gotten worse, any ideas? I dont know much about trannys. Especially M6's. :suicide:
